MAGAZINE CAMERA.

SPEGIFIGATIUN forming part of Letters Patent No. 700,792, dated MayApplication filed October 31. 1901. Serial No. 80,637. (No model.)

To all whom it may concern:

Be itknown that I, DAVID ABRAHAM Low- THIME, a subject of the King ofGreat Britain and Ireland, residing at 17 and 1S Paradise street,Finsbury, in the city and county of London, England, have invented a newand useful Improvement in Magazine-Cameras (for which I have applied forLetters Patent in Great Britain, No. 7,807, bearing date the 17th day ofApril, 1901; in Germany, bearing date August 13, 1901; in France, No.302,495, hearing date August 30,1901, and in Belgium, No. 125,908,hearing date August 30, 1901,) of which the following is a full andcomplete specification.

This invention relates to a new or improved means for loading andunloading magazine, hand, or other photographic cameras with plates orcut films in daylight without the necessity of using a dark room.

In the accompanying drawingsgvhich illustrate by way of example onemeans of carrying this invention into practice, Figure 1 is a view insectional side elevation of a handcamera charged or loaded with platesor films ready for exposure; and Fig. 2 is a similar view showing theplates or films ready for withdrawal from the camera after exposure; andFig. 3 is a sectional view, in side elevation, on an enlarged scale, ofa packet or box of plates or films packed for transport and ready forinsertion within the camera.

Similar letters refer to similar parts throu gh-' out the several views.

The case or box a (see Fig. 3) is formed of non-actinic or light tightmaterial of a size and shape adapting'it to contain the desired size anddesired number of plates on or cut films, together with their requisitebackingsheets holders, or their equivalents. The lid of this case or boxis formed from a strip a of non-actinic or light-tight material,preferably ruby-colored fabric, which is attached to the box by oneormore covering-strips c of paper or other material appreciably weaker orthinner than the strip a. The strips of paper a are secured to the boxand strip a by any suitable adhesive, the arrangement being such that nopart of the lid is secured directly to the box or case, but only throughthe medium of the paper or other material. The strip a after forming thelid to the case or box is bent or doubled on itself at a and thecontinuation thereof passes over the lid and terminates in asuitably-stiffened tab or end. For convenience in manufacture the box isformed from two parts, the one to which the strip a is attached slidingover the other or bottom part. This latter partis provided with a holeorcut-away portion a so as to allow of the plates being automaticallyfed forward by means of a spring when in position in the camera. A caseor box so constructed and charged alternately with plates mor films andbacking-sheets 5c, holders, or their equivalent is carried till requiredfor use in any suitable box.

The camera Z) for use with this system of changing plates or films isprovided at its back end with a hinged or removable door 0 to allow ofplacing the sealed case or box a, containing the plates :0 or films,onto a ledge or shelf d, provided within the camera at a certaindistance above the bottom thereof.

In order to charge or load the camera, the end door 0 is opened orremoved and the sealed case or box (0, containing the plates or films,is inserted in such a manner that the attached strip or tab of materiala is doubled over the front edge of the ledge or shelf (Z and broughtoutside over the top 6 of a sliding box 6, placed within the camerabetween the bottom thereof and the ledge or shelf 61, as shown in dottedlines on Fig. 1 of the drawings. The box 6 is held within the camera bya spring bolt or catch e and is provided with a hinged sliding lid 6,which can be held in its closed position by means of a button a engaginga slot on its under side, and in its open position by a button 6,carried on the under side of the camera. This box 6 is for the purposeof. receiving the plates or films a; after exposure, together with theirbackingsheets or equivalents. (See Fig. 2.) The case or box a of platesor films is placed in position, as shown, so that the front edges of thesides of the case or box 66 engage or contact with ribs or projectionsZ), formed on the sides of the camera. The end door 0, which is providedwith a spring 0 on its inner side in order to feed the plates or filmsforward to the plate-changing device f, which may be of any suitableconstruction, but which is preferably provided with one or more springsf on its under side, adapted to guide and engage the plates afterexposure, is then replaced. The box 0, adapted to contain the exposedplates or films, slides light-tightly into the bottom of the camera, andwhen in position, with its lid 6' closed, the strip or tab (1/, attachedto the sealing or covering part of the case or box a, is pulled so as tobe entirely withdrawn, thus uncovering the first plate or film ready forexposure. The hinged lid 6 of the box 6 is then slid open and preferablyfolded down and clipped under the bottom of the camera, as shown inFig. 1. The back end of the camera I) is provided with an auxiliary orouter door g, inclosing both the end door 0 and sliding box c. When allthe plates to or films have been exposed, (see Fig. 2,) the lid 6 of thesliding box 0 is closed, which is then withdrawn from the camera Z).

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A means for loading and unloading photographic cameras with platescomprising a case adapted to contain the plates placed alternatelytogether with their backing-sheets and having its front side formed froma flexible strip of non-actinic material so attached as to be easilytorn away from the case in order to uncover the foremost plate therein,and a camera provided at its back end with a door for introducing andwith a shelf for supporting the said case and further provided with abox sliding light-tightly therein so placed as to admit of receiving theplates after their exposure, the said sliding box being provided with asliding lid, as set forth.

A photographic camera comprising a transversely-arranged shelf (Zforming a ledge for supporting the plates, a box c-with movable lidesliding light-tightly within the camera between the bottom thereof andthe shelf d and adapted to contain the plates after exposure, a door 0formed to allow access to the plate-holding compartment formed betweenthe walls of the camera and the shelf (Z in combination with a case aadapted to be placed on the shelf (Z within the camera and to containplates .4 placed alternately with their backing-sheets w and having afront side formed from a flexible strip a of nonactinie materialattached to the case by covering-strips a of weaker material than thestrip a, which strip a is doubled 011 itself in order that its free endmay be passed over the shelf (Z to protrude from the camera and on beingpulled uncover the first plate .ready for exposure, as set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
